Empire has the first look at Johnny Depp and Christian Bale as John Dillinger and lawman Melvin Purvis in Michael Mann's Public Enemies. Based on the images, here's my idea for the trailer narration:
One is a criminal gang leader; the other, an FBI agent. In their apartment they're best friends, but on the street they're about to kill each other. (Boi-yoi-yoi-yoing!) Johnny Depp and Christian Bale are: Public Enemies. (SPLAT!)
How about it, Michael Mann? What it lacks in gravitas it makes up for in spring sound effects.
